Walur (Amorphophallus variabilis) is a plant species in Araceae, herbaceous with tubers, reproducing vegetatively and generatively, small tubers and itching in the mouth which people do not want to eat unless forced to, grows wild but is often cultivated in yards when there is famine.

A. variabilis with a vegetative part having a height of 0.3-1.5 meters, having a green or brown or purplish or black color with bright green or dark green or black or white stripes. Leaves with 1-2 strands. The leaf blade has three parts, each part is further divided in elongated or lanceolate with a tapered tip or tail-like.





Flowers appear when the vegetative organs wither and grow in an independent cob. Stalks long and slender, often with rough pimples. Base with some protective leaves. The flower is triangular elongated with a pointed tip. The top of the cob is elongated. The fruit is crowded, green to red-orange and has 1-2 seeds.

Tubers are yellow and itchy in the mouth when eaten. The tubers produce shoots that can be separated. In times of famine, the tubers are sliced into small pieces and then boiled for eating. The tubers are also grated or ground and cooked in banana leaves.

Leaves, petioles, fruit and fruit cobs are cooked as vegetables. Leaves as food for fish in ponds. Tubers are rich in mannan, a carbohydrate that can be made into konnyaku.
